Hi, The current issue of Ariadne (http://www.ariadne.ac.uk/issue57/) which has just been published contains an article about the "SeeAlso" linkserver protocol: Jakob Voß: "SeeAlso: A Simple Linkserver Protocol", Ariadne Issue 57, 2008. http://www.ariadne.ac.uk/issue57/voss/ SeeAlso combines OpenSearch and unAPI to a simple API that delivers a simple list of links. You can use it for dynamically embedding links to recommendations, reviews, current availability, reviews, search completion suggestions, etc. It's no rocket science but I found a well defined API with reusable server and client better then having to hack a special format and lookup syntax for each single purpose. The reference client is written in JavaScript, see http://ws.gbv.de/seealso/seealso.js and http://ws.gbv.de/seealso/javascript-client/doc/ and the reference Server is written in Perl, see http://search.cpan.org/dist/SeeAlso-Server/ - but implementing it in any other language should not be complicated. I'd be happy to get some feedback either in form of code, applications, or criticism :-) I noted that SeeAlso::Server is the only implementation of unAPI at CPAN so far - if someone is interested, we could extract parts into an independent unAPI package. The WWW::OpenSearch::Description package is also worth to consider for use in SeeAlso::Server.
